Town twinning, also known as sister cities, is a concept whereby towns or cities in geographically and politically distinct areas are paired, with the goal of fostering human contact and cultural links between their inhabitants. In the European Union, such pairs of towns are known as friendship towns, partner towns or twin towns. In North America, India, Australasia and Asia, the term sister cities is used for the same concept and brother cities is the term in the former Soviet bloc. Sister cities often (though by no means always) have similar demographic and other characteristics.
